  • The number of duplicate cards will be visible on a card within a set.
  • Collecting duplicate cards will grant duplicate card stars.
  • Obtaining a duplicate card increases your duplicate card stars balance by the same amount as the star value of that duplicate card.
  • You can collect duplicate card prizes depending on the number of duplicate card stars you collect.
